Colin Kaepernick has thrown eight touchdown passes and one interception in San Francisco's five-game win streak.

In the past five games, all 49ers wins, Kaepernick has thrown eight touchdown passes and has just one interception.

Furthermore, San Francisco’s third-year pro has posted a 108.6 quarterback rating or better in four of those games. The lone exception was a 67.5 rating against the Seattle Seahawks, the NFL’s No. 1 overall defense.

Kaepernick currently has an 89.9 quarterback rating and has thrown for 2,887 yards on the year. He’s thrown 19 touchdowns and has eight interceptions in 15 starts this season.

In the past three weeks, Kaepernick has raised his game especially, according to offensive coordinator Greg Roman.

“I think he’s done a really good job the past three games of being decisive,” Roman said. “But, then again, I think he does most all the time. And, if he’s not we’ve got to give him better plays. That means nobody’s open or something along those lines. But, no, he’s doing a really good job and he’s just looking to improve.”

In addition to being sound in the passing game, Kaepernick also has 165 rushing yards during the 49ers winning streak. The athletic quarterback totaled 335 rushing yards in the previous 10 games.

Kaepernick is 38 yards shy of breaking Steve Young’s single-season rushing record for a 49ers quarterback.

This week, the 49ers will face the NFL’s No. 1 ranked rushing defense in the Arizona Cardinals.

Kaepernick said there will be no adjustments to San Francisco’s run schemes. The 49ers will try to overpower the Cardinals now that the line is fully healthy and has left guard Mike Iupati back in the lineup.

“We just have to go out and execute like we have been doing,” Kaepernick said.

The 49ers executed the run game to perfection in the first meeting against Arizona.

With a 2-point lead late in the fourth quarter of a Week 6 matchup at Candlestick Park, the 49ers put together a season-high 18-play, 83-yard scoring drive, capped by a 6-yard Kendall Hunter touchdown run.

“It really comes down to how the players executed,” Roman said when asked to look back at the drive. “We converted some key third downs, I believe a fourth-and-short there, but really came down to the execution on the field. And when you see that kind of execution it makes it pretty easy. That was a heck-of-a drive and boy that was a long time ago though, that was a long time ago. We’re focusing on this week, but that was definitely much needed at that point. Players stepped up big time.”

San Francisco will need to step up again with playoff implications on the line in a Week 17 road game in Arizona. With a win, the 49ers are in the mix for home-field advantage and a division title. The Cardinals, likewise, have much at stake. If New Orleans loses and Arizona can knock off San Francisco, then the Cardinals will earn the NFC’s No. 6 seed, giving the NFC West an impressive number of three playoff teams.

“It’s the toughest division in football,” Kaepernick said. “There are a lot of great teams, a lot of great players in this division.”

The 49ers know the challenge at hand and the starting quarterback aims to keep leading the offense towards another Super Bowl run.

“We have to keep our momentum going into playoffs,” Kaepernick said. “We aren’t in full control of where we’re going to be seeded. So, we have to go out and win to keep our momentum.”
